Used primarily as a chemical intermediate in the synthesis of agrochemicals and pharmaceuticals. It serves as a protected form of carbamic acid in organic reactions where controlled release of isocyanate or amine functionalities is required. Commonly employed in the preparation of ureas and urethanes through thermal or catalytic decomposition. Its cyano and tert-butyl groups provide steric stability, making it suitable for use in peptide synthesis and other sensitive multi-step reactions. Also utilized in polymer chemistry to introduce carbamate linkages without side reactions.
